Skin Cancers, Precancerous Lesions & Benign Growths

• Skin Cysts (Epidermoid, Pilar, Sebaceous): Benign, sac-like growths under the skin containing fluid or semi-solid material. May become inflamed or infected and sometimes require removal.
• Squamous Cell Carcinoma (SCC): A common form of skin cancer developing in the squamous cells. Often appears as a firm, red nodule or a flat lesion with a scaly, crusted surface on sun-exposed areas. Can grow more rapidly than BCC.
• Melanoma: The most serious type of skin cancer, developing in melanocytes. Early detection is crucial. Look for asymmetry, irregular borders, color variation, diameter >6mm, and evolving moles (ABCDEs).

Acne, Rosacea & Follicular Disorders

• Acne Scars (Atrophic, Hypertrophic, Keloidal): Permanent textural changes and indentations (atrophic), raised scars (hypertrophic), or overgrown scars (keloidal) that can result from severe or picked acne.
• Hidradenitis Suppurativa (Acne Inversa): A chronic, recurrent inflammatory skin condition featuring painful, deep-seated lumps, abscesses, sinus tracts, and scarring, typically in areas where skin rubs together (axillae, groin, under breasts).

Nail Disorders (Onychopathies)

• Lichen Planus of the Nails: Nail involvement in lichen planus, which can cause thinning, ridging, splitting, pterygium formation (scarring from nail fold to bed), or even nail loss.
• Ingrown Toenails (Onychocryptosis): A condition where the corner or side of a toenail grows into the soft flesh, causing pain, redness, swelling, and potential infection.
• Nail Psoriasis: Psoriasis affecting the fingernails and toenails, causing pitting, discoloration (oil drop sign), thickening, onycholysis (separation from bed), and subungual hyperkeratosis.

This list is not exhaustive. For personalized advice regarding your specific dermatological condition, please consult with Dr. Katarina Fiala.

• Mohs Micrographic Surgery for High-Risk Skin Cancers: Specialized surgical technique for removing complex or high-risk skin cancers (especially on the head, neck, hands, feet, genitals) with maximal tissue preservation by examining 100% of the surgical margin intraoperatively.
• Laser & Light-Based Treatments (IPL, Fractional Lasers, Ablative/Non-Ablative Resurfacing, Vascular Lasers, Pigment Lasers): Utilizing various laser (e.g., CO2, Erbium, Pulsed Dye, Nd:YAG, Alexandrite, Picosecond) and Intense Pulsed Light (IPL) technologies for skin rejuvenation, wrinkle reduction, scar improvement, hair removal, treatment of vascular lesions (e.g., spider veins, rosacea, port-wine stains), and pigmented lesions (e.g., sun spots, tattoo removal).
• Cryosurgery (Liquid Nitrogen Treatment for Pre-cancers & Benign Lesions): Application of extreme cold (liquid nitrogen) to destroy benign (e.g., warts, seborrheic keratoses) or precancerous skin lesions (e.g., actinic keratoses).
• Nail Surgery (e.g., Ingrown Toenail Removal/Matrixectomy, Nail Biopsy, Tumor Excision): Surgical procedures to treat painful or diseased nails, including permanent correction of ingrown toenails or removal of nail unit tumors.
• Electrodessication & Curettage (ED&C) for Superficial Skin Cancers & Benign Lesions: Surgical procedure to scrape away superficial skin lesions (e.g., some BCCs, SCCs in situ, warts) and cauterize the base.
• Botulinum Toxin Injections (e.g., Botox®, Dysport®, Xeomin®) for Wrinkles & Hyperhidrosis: Injectable treatments to temporarily relax facial muscles and reduce dynamic wrinkles (e.g., frown lines, crow's feet, forehead lines), or to treat excessive sweating (hyperhidrosis).
• Nail Disorder Treatment (Fungal Infections, Psoriasis, Lichen Planus, Ingrown Nails, Tumors): Diagnosis and management of conditions affecting the nails, including infections, inflammatory disorders (like nail psoriasis or lichen planus), structural abnormalities, ingrown nails, and benign or malignant nail unit tumors.

Are consultations and dermatological treatments with Dr. Fiala, a Dermatologist, covered by Ontario Health Insurance Plan (OHIP) in ON?

Medically necessary consultations with a licensed Dermatologist like Dr. Fiala, diagnostic procedures (e.g., skin biopsies), and treatments for provincially insured skin conditions (e.g., psoriasis, severe eczema, skin cancer, infections) are generally covered by Ontario Health Insurance Plan (OHIP) in ON when a referral from a family doctor is in place. Purely cosmetic procedures (e.g., Botox for wrinkles, most laser hair removal, fillers for aesthetic enhancement) are typically not covered and are self-pay. It's crucial to discuss coverage specifics for any proposed treatment with Dr. Fiala's office or Ontario Health Insurance Plan (OHIP) beforehand, especially if there's a potential cosmetic component.

Do I need a referral to see Dr. Fiala, a Dermatologist?

Yes, for medically necessary dermatological care covered by the provincial health plan, a referral from your family physician or another specialist (e.g., an ER doctor for an acute issue) is almost always required to see a Dermatologist such as Dr. Fiala. This ensures coordinated care and that your visit is appropriate for specialist assessment. Some dermatologists may offer consultations for uninsured cosmetic services without a referral, but these would be a direct cost to you. Always check with the clinic regarding their specific referral policy.

When should someone consider seeing a Dermatologist like Dr. Fiala?

A referral to a Dermatologist like Dr. Fiala is often recommended by a family physician for: any new or changing moles or skin growths; persistent or severe skin rashes (e.g., eczema, psoriasis) not responding to initial treatments; severe or cystic acne; chronic hives; significant hair loss or scalp disorders; problematic nail conditions (e.g., persistent fungal infections, unusual changes); suspected skin infections; or for expert skin cancer screening, especially if you have risk factors like a personal or family history of skin cancer, numerous moles, or significant sun exposure. Early consultation can be key for effective management and diagnosis.

If Dr. Fiala recommends phototherapy, what does that involve?

Phototherapy, also known as light therapy, is a medical treatment where your skin is exposed to specific wavelengths of ultraviolet (UV) light under strict medical supervision. Dr. Fiala might recommend it for conditions like psoriasis, eczema, vitiligo, or cutaneous T-cell lymphoma. Treatments are typically given 2-3 times a week in a specialized light cabinet or with a handheld device for smaller areas. The type of UV light (e.g., Narrowband UVB, PUVA) and treatment duration are carefully controlled. It works by reducing inflammation and slowing down the rapid growth of skin cells. You'll be given specific instructions, including eye protection.

What kind of sunscreen does Dr. Fiala recommend?

While specific brand recommendations can vary, Dr. Fiala would likely advise choosing a broad-spectrum sunscreen that protects against both UVA and UVB rays, with an SPF (Sun Protection Factor) of 30 or higher. For daily use, a lighter formulation might be preferred, while for prolonged outdoor activities, water-resistant sunscreen is important. Consider your skin type: individuals with sensitive skin might prefer mineral-based sunscreens containing zinc oxide or titanium dioxide. The most important thing is to apply sunscreen generously and reapply it every two hours, or more often if swimming or sweating. Dr. Fiala can provide personalized recommendations based on your skin type and lifestyle during your consultation.

How should I prepare for my first dermatology appointment with Dr. Fiala?

To make the most of your first visit with Dr. Fiala, it's helpful to: 1. Make a list of your skin concerns, symptoms (e.g., itch, pain, duration), and any treatments you've already tried (both prescription and over-the-counter). 2. Bring a list of all your current medications, including vitamins and supplements. 3. Be prepared to discuss your personal and family medical history, including any history of skin cancer or significant skin conditions. 4. For a full skin exam, it's best to wear loose, comfortable clothing that is easy to remove and avoid wearing makeup or nail polish. 5. If your concern involves a rash that comes and goes, taking clear photos when it's visible can be very helpful. 6. Write down any questions you have for Dr. Fiala.

What is the difference between a Dermatologist and an Esthetician?

A Dermatologist, like Dr. Fiala, is a medical doctor (MD) who has completed medical school followed by several years of specialized residency training in dermatology. They are qualified to diagnose and treat over 3,000 diseases of the skin, hair, and nails, prescribe medications, perform surgical procedures (like skin cancer removal), and manage complex skin conditions. An Esthetician (or Aesthetician) is a skincare professional trained in cosmetic skin treatments and services that improve the appearance of the skin, such as facials, superficial chemical peels, microdermabrasion, waxing, and makeup application. They are not medical doctors and cannot diagnose skin diseases, prescribe medications, or perform medical or surgical procedures.
